Mexico's $1.3 trillion economy has become increasingly oriented toward manufacturing in the 20 years since the North American Free Trade Agreement (NAFTA) entered into force. Per capita income is roughly one-third that of the US; income distribution remains highly unequal. Mexico has become the United States' second-largest export market and third-largest source of imports. In 2013, two-way merchandise trade reached nearly $507 billion. Mexico has free trade agreements with over 50 countries including Guatemala, Honduras, El Salvador, the European Free Trade Area, and Japan - putting more than 90% of trade under free trade agreements. In 2012 Mexico formally joined the Trans-Pacific Partnership negotiations and formed the Pacific Alliance with Peru, Colombia and Chile. Mexico's current government, led by President Enrique PENA NIETO, emphasized economic reforms during its first year in office, passing education, energy, financial, fiscal and telecommunications reform legislation. The three-party "Pact for Mexico" reform agenda aims to improve competitiveness and economic growth across the Mexican economy.
